@sdetweil thanks for pointing out pm2 error logs. Will have a look after some sleep. Uploading log here: [0_1591166110878_MagicMirror-error.log](Uploading 100%)

Been tickering w/ this on and off for an annoying couple of months now and haven’t had any luck getting hotword to work. I scrapped everything and started from scratch reinstalling everything after reformatting the SD card.

Encountered blackscreen. Commented out different sections of config until narrowed it down to Hotword module config. Ran syntax config check utility and found no syntax errors.

I’ve uploaded my config.js file. Please help.

I’ve tried every variation. I’ve scrapped everything. Starting from scratch again. I guess I’ll come back if still an issue.
